Darth Vader, born as Anakin Skywalker is a fictional character in the Star Wars universe. He is the secondary antagonist of the original trilogy, though he later redeems himself and the main protagonist of the prequel trilogy which shows us how he became evil.
The character was created by George Lucas and has been portrayed by numerous actors. His appearances span all six Star Wars films, and he is an important character in the expanded universe of television series, video games, novels, literature and comic books. Originally a Jedi prophesied to bring balance to the Force, he falls to the dark side of the Force and serves the evil Galactic Empire at the right hand of his Sith master, Palpatine (also known as Darth Sidious). He is also the father of Luke Skywalker and Princess Leia Organa.
The American Film Institute listed him as the third greatest movie villain in cinema history on 100 Years... 100 Heroes and Villains, behind Hannibal Lecter and Norman Bates..
